I'm a Mac user and even I don't like Safari. I find it to be the Mac version of IE - it's mac-esqueness manifests in being less offensive, and working better, but it's still overly simplistic, and not what I'd choose to use.

I use Camino on my mac, though that's largely a result of the fact that it's on the machines at University, it's less annoying than Safari, I don't want to install Opera every time I start up a machine, and it's easier to associate Camino with using Macs. As soon as I leave Uni though, it'll probably be Opera all the way.
